3.5 RDA analysis
The DCA of the insect pollinator community projected a gradient length of 2.4 indicating RDA was the appropriate ordination method. Environmental factors; Elevation and flower resource abundance was found to be the significantly associated environmental factor for the pollinators (ANOVA, p < 0.05) (Table 4) The relation of the top 15 most abundant pollinators 9 five from each group) with these significant environmental variables are shown in RDA (Figure 5). Two canonical axes of RDA analysis explained the variance by 12.828 % in the pollinator–environmental interaction where the first axis and second axis accounted for 2.118 % and 10.71% of the variance respectively. Managed habitat types represented the higher abundance of flowers associated with the high number of Apis cerana andApis mellifera . On the other hand, Pieris canidia was found associated with both open trail and grassland and Vanessa cardui in a managed habitat. Bombus eximius , Bombus flavescens , Eristalis tenax , and Ypthima baldus were more associated with the forest trail which was relatively humid area. Likewise, Melanostoma univittatum and Episyrphus viridaureus were associated with the open trail whereasEpisyrphus balteatus was close to grassland and managed habitat.
